If I disable og:url in your plugin settings it partially debugs and pulls wrong featured image. If I enable og:url it can’t debug at all and it shows error. “Object at URL ‘http://mixeta.net/dogadaj/tkototamosvira-tobogan/’ of type ‘article’ is invalid because the given value ” for property ‘og:url’ could not be parsed as type ‘url’.”

So can you make it so it works with the events calendar plugin so events can be also be debuged.
